[sdiy] pseudo-random tone generator

[Ian Smith]

Hi all, 

I've been searching around for a link that I stumbled upon a while ago that I can't find now. It was basically a project prompt for a Pseudo-Random Tone Generator for a college electronics class. I don't remember the college but I do remember that it involved an LM556, a couple of CD4024s, one or two CD4021s, a couple of CD4051s, and a CD4070. and one op-amp.

I have a partial schematic scrawled somewhere in one of many notebooks. If anyone has any clue what I'm talking about and knows where to find this thing, I'd appreciate it.

Thanks,

-Ian
